A hoop house typically costs $300-$2,500 for a small DIY structure, $3,000-$12,000 for a common backyard or small-farm build, and $15,000-$60,000 or more for a large commercial high tunnel. Size, frame strength, covering, site preparation, and whether installation is included account for most price differences.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small DIY hoop house | $300 | $900 | $2,500 | About 6 x 8 to 12 x 20 ft; basic frame and plastic |
| Farm-size high tunnel | $3,000 | $8,000 | $15,000 | About 20 x 48 ft; price depends on kit contents and anchoring |
| Large installed tunnel | $15,000 | $30,000 | $60,000+ | About 30 x 96 ft; stronger frame, site work, and installation can raise the bill |
| Cover replacement | $150 | $450 | $1,200 | Plastic film only; size, thickness, and delivery affect price |
Typical hoop house prices by size and scope
A simple 6 x 8 ft backyard hoop house can cost $300-$800 with a basic kit or $150-$500 in materials for a careful DIY build. A 10 x 20 ft structure commonly runs $700-$2,500 for materials, while a 20 x 48 ft farm tunnel often costs $3,000-$8,000 as a kit before extensive site work or paid installation.
Installed pricing is higher because it may include delivery, anchoring, doors, ventilation, and labor. A 20 x 48 ft tunnel installed on a level, accessible site may total $6,000-$15,000; a large 30 x 96 ft structure can reach $25,000-$60,000 or more with reinforced framing and accessories. For a useful first budget, separate the bare kit price from the finished, installed price.
Per-square-foot estimates are roughly $2-$6 for basic DIY materials, $4-$10 for a standard kit, and $8-$20 or more for a professionally installed structure. These rates are broad comparisons rather than fixed bids: smaller houses tend to cost more per square foot, and commercial-grade components can push a project above the range.
Assumptions: U.S. pricing, standard polyethylene covering, ordinary access, and no major grading, utility work, or greenhouse heating system.
What frame, film, and installation add to the quote
A hoop house quote may cover only the frame and covering, or it may include doors, roll-up sides, ground posts, delivery, and assembly. Confirm the included components before comparing offers; a low kit price may omit anchors, end walls, or the hardware needed to secure the plastic.
| Quote component | Typical price | What changes the charge | Common billing basis |
|---|---|---|---|
| Galvanized frame and bows | $1,200-$4,500 | Width, steel gauge, bow spacing, bracing | $2-$6 per sq ft |
| Polyethylene film | $150-$1,200 | Thickness, UV rating, width, number of layers | $0.10-$0.60 per sq ft |
| End walls, doors, and vents | $300-$2,500 | Door count, framing material, ventilation type | $100-$900 per feature |
| Anchors and ground posts | $250-$1,500 | Soil conditions, wind exposure, post depth | $5-$25 per anchor |
| Assembly labor | $1,000-$6,000 | Structure size, crew, access, site readiness | $50-$100 per worker-hour |
| Delivery and site work | $200-$3,000 | Distance, unloading needs, grading, drainage | $100-$1,500 per service |
For labor, a two- or three-person crew may spend 12-30 hours assembling a small or medium tunnel, while a larger project may require 40-100 crew-hours. At $50-$100 per worker-hour, labor can account for several thousand dollars of the installed total.
Ask for itemized pricing on the frame, film, anchors, labor, delivery, and accessories. This makes it easier to identify whether two quotes specify the same steel, plastic life, wind bracing, and level of completion.
Width, steel gauge, and plastic thickness change the price
Width is a major cost driver because wider tunnels need longer bows and often require stronger framing. A 12-16 ft wide garden tunnel can be a few hundred to a few thousand dollars in kit form; moving to a 20-30 ft farm structure can multiply the frame and covering expense, especially when the design includes frequent bows or heavy bracing.
Frame specifications matter in exposed locations. Light-duty tubing may suit a sheltered garden, but a 30 ft wide tunnel or a site with strong winds or snow loads may need heavier-gauge steel, closer bow spacing, cross-bracing, and deeper anchors. Those upgrades can add $500-$5,000 or more depending on size and the engineering required.
Covering thickness and construction also affect replacement expense. A single layer of greenhouse film is less costly than a double layer inflated with a blower, which can add roughly $300-$1,500 for film and equipment on a medium tunnel. UV-stabilized film commonly lasts about 3-5 years, though climate, wind, and handling affect service life.
Site conditions can change the estimate even when the structure stays the same size. Sloped ground, rocky soil, poor drainage, or limited truck access may require grading, trenching, extra anchors, or manual material handling. Price the tunnel for local wind and snow conditions rather than choosing a frame by width alone.
How many labor hours does a 20 x 48 ft tunnel need?
A standard 20 x 48 ft kit may take a prepared crew roughly 20-50 total worker-hours to assemble, with more time needed for end walls, doors, roll-up sides, or difficult anchoring. At common contractor rates of $50-$100 per worker-hour, the labor portion might be $1,000-$5,000 before travel, equipment, or site preparation.
DIY work can reduce the cash outlay, but the frame is typically assembled by multiple people. Lifting bows, keeping them aligned, and tensioning a large sheet of film are awkward tasks; poor installation can lead to loose covering or frame stress. A small DIY build may take a weekend, while a farm tunnel can require several workdays depending on crew size and weather.
Contractor minimums can make a small installation seem expensive. A crew may charge a $500-$1,500 minimum for mobilization, even if the structure takes only a few hours to assemble. Compare the installed total, not just the hourly labor rate.
Regional labor and delivery can shift U.S. quotes
Labor, freight, and local demand make installed prices vary by location. In lower-cost rural markets with nearby suppliers, a standard kit and assembly may fall near the lower end of the ranges above. Urban and high-cost coastal areas can run about 10%-30% higher, particularly where contractor labor, permits, or delivery access are expensive.
Remote farms may also pay more even when local labor rates are modest. Oversize bundles, a long trip from the supplier, or the need for specialized unloading can add $200-$1,500 or more. Cold, snowy regions may require stronger framing and anchoring, while high-wind areas can call for added bracing. These are design and delivery differences, not just regional markups.
Local agricultural programs sometimes offer cost-share assistance for season-extension structures, but eligibility and funding vary by state and program. A rebate or grant should not be assumed in a contractor quote; buyers should verify current requirements with the relevant local or state agency. Request a delivered price that names freight, unloading, and any required structural upgrades.
Extra doors, irrigation, and grading raise the finished price
Accessories are easy to overlook when estimating a complete growing setup. Manual roll-up sides may add $300-$1,500, while motorized ventilation can add $500-$2,500 or more. A second door, insect screening, shade cloth, benches, or an inflation blower may add another $100-$1,500 each depending on size and equipment quality.
Basic drip irrigation for a small tunnel may cost $100-$500 in supplies; a larger, zoned system with filtration and a pump can run $500-$2,500. Heating is a separate project: a simple portable heater may cost $100-$600, while a larger fuel-fired system and controls can cost $1,000-$5,000 or more, excluding fuel and electrical work.
Clearing and leveling a modest site can cost $300-$2,000. Major grading, drainage, or rock removal may exceed $3,000. Removing an old tunnel can add $200-$1,500, particularly if the frame must be dismantled and waste hauled away. Include site work and climate equipment only when the growing plan requires them.
Three quote examples for backyard and farm tunnels
A 10 x 20 ft backyard kit with light galvanized bows, one layer of film, one door, and DIY assembly might cost $900-$2,000 for materials. With $400-$1,000 in contractor assembly and delivery, the total could be $1,500-$3,300 on a level site.
A 20 x 48 ft farm tunnel with standard steel framing, UV-rated film, two end doors, manual roll-up sides, and anchors may cost $4,500-$8,500 as a kit. Adding 30-50 worker-hours at $60-$85 per hour, plus $300-$800 delivery, puts an ordinary installed estimate around $6,600-$13,500 before irrigation or grading.
A 30 x 96 ft commercial tunnel with heavier framing, reinforced end walls, double-layer film, ventilation, and professional installation may total $25,000-$55,000. A difficult site, snow-load upgrades, mechanized ventilation, or extensive grading can push the project above $60,000. These examples describe typical scopes, not guaranteed bids.
Compare quotes only after matching dimensions, frame strength, film specifications, included doors, anchoring, and installation scope. A lower quote may simply leave out a costly part of the finished structure.
Where a hoop house budget can be trimmed safely
Keep the footprint close to the area needed for crops, access paths, and equipment. Reducing a tunnel from 30 x 96 ft to 20 x 48 ft can cut frame, film, freight, and assembly expenses substantially. Avoid adding height, a second door, or motorized ventilation unless the crop, access needs, or climate justify the upgrade.
Choose a standard kit size when it fits the site; custom widths and lengths can raise fabrication and freight charges. Compare film warranties and UV ratings rather than selecting the cheapest plastic automatically. A modest film upgrade may be worthwhile if it extends useful life, but double-layer film and a blower are not necessary for every short-season or unheated setup.
Prepare the site before the delivery date by clearing vegetation, confirming truck access, and checking drainage. Ask the supplier which ground preparation is required so paid crews are not waiting while the area is leveled. If the project is small, DIY assembly can reduce labor costs, provided the builder has enough helpers and follows the anchoring instructions.
Get at least three itemized quotes and verify whether taxes, delivery, disposal, permits, and site work are included. Permits are not required everywhere for agricultural tunnels, but local rules may depend on structure size, anchoring, zoning, or distance from property lines. The most reliable savings come from controlling scope and comparing equivalent specifications, not removing essential anchors or weather protection.
